Ann Alexander (wife of Moses Moore) was not married to Samuel Swann. I believe this is a mistake which I made while researching many years ago.
I do not know about John Robinson's marriage to a Nancy Thanley. I doubt this. Look at the marriage date for Abigail Moore and John Robison/Robinson, then look at the birthdate for the child of John Robinson and Nancy Thanley. I believe they are different people.
John Robinson has a Revolutionary War pension record with his children listed. Moses Moore left a will mentioning his four children: Abigail, James, William and Mary Scott.
I am not sure who Ann Alexander's parents were, but she seems to be closely related to John McKnitt Alexander.
John Robinson's father was Robert Robison/Robinson and his mother was Isabella Harris. I believe the Robinson Rock house in Charlotte, NC is the home of Robert and Isabella Robison. Robert Robison/Robinson received a land grant on Reedy Creek in Charlotte, NC. John's brother is also named Robert Robison/Robinson. He married Deborah Alexander and lived in SC. This Robert was also in the Revolutionary War. Robert and Deborah died leaving young children.
